摘要： A circulating type of automatic document feeding apparatus comprising a document hopper which is adapted to take out the top document from the hopper or take it out from the bottom to return in onto the topmost side, a first carrying means for carrying the document form the document hopper to a first exposure portion, a document presentation portion having the first exposure portion and the second exposure portion, a second carrying means which is equipped with an inside and outside inverting means for inverting the carrying direction of the document between the first exposure portion and the second exposure portion, and a third carrying means for returning the document to the document hopper from the second exposure portion. One face of the duplex document may be exposed in the first exposure portion to continuously expose the other face thereof in the second exposure portion, so that the copying operation of the duplex document may be effected at higher speeds and furthermore with considerably reduced operations on the part of the operator.

摘要： A photoreceptor of an electrophotographic copying machine is rotatably supported by a mounting member. The mounting member is rotatably supported by a supporting member which can slide out of the housing of the copying machine. The supporting member also supports a developing station. When the supporting member is pulled out of the housing, the developing station can be displaced on the supporting member away from the photoreceptor and the mounting member can be rotated so as to expose the photoreceptor such that its surface becomes accessible from outside.

摘要： A copying machine which produces one or more copied sheets by utilizing an electronic photographic method, wherein a coil shaped developing electrode is provided close to the traveling path of the photosensitive paper or the surface of the dram within the developing section of the device. Electric lines of force caused by an electrostatic latent image formed on the photosensitive paper or the dram are uniformly intensified as the paper or the dram pass near the developing electrode, whereby the edge development effects are suppressed and the contrast of the developing image is amplified in order to obtain a clean copy. A developer is replenished onto the photosensitive paper or the surface of the dram through clearances provided within the coil shaped developing electrode.
摘要翻译：一种通过利用电子照相方法产生一个或多个复印片材的复印机，其中线圈形显影电极设置在感光纸的行进路径或设备的显影部分内的表面的表面附近。当由于纸张或电影通过显影电极附近时，由形成在感光纸或电视机上的静电潜像引起的电力线被均匀地增强，从而抑制了边缘显影效果，并且显影图像的对比度被放大以获得干净的副本。显影剂通过设置在线圈状显影电极内的间隙而补充到感光纸上或者电极表面上。
